Question

give reason why it is difficult to break young tender stem compared to woody stem of a plant

Answer 1

Answer:

It is because a woody stem is a brittle stem, making it easy to break it.

A young tender stem is very flexible stem making it very difficult to break

Answer 2

Answer:

A young tender stem, which is still green in colour, has living cells, which are still capable of growth. These cells are called Meristem. On the other hand, a woody stem of a plant is composed of Sclerenchymatous cells, which are generally dead cells. The young tender stem, thus has high elasticity and tensile strength, with which, it can resist from being torn, whereas the woody stem lacks this elasticity and hence, it can easily be broken.
